본 고안은 소형 모터의 정류자장치, 특히, 정류자편의 단자부에 길이방향에 대하여 직각방향의 단면적이 다른 부분보다도 작게 되도록 한 협애부(狹隘)를 설치함과 동시에 그 협애부에 리드선 결합 용이화 수단을 마련하고 상기 협애부에서 상기 단자부를 꾸부려서 전기자 권선의 리드선을 협착하고 또한 리드선과 상기 단자부를 저항 용접에 의해 용착시키도록 한 소형모터의 정류자장치에 관한 것이다.The present invention provides a narrowing part having a cross-sectional area perpendicular to the longitudinal direction of a commutator device of a small motor, in particular, a terminal part of the commutator piece smaller than the other part, and at the same time, a means for facilitating lead wire coupling at the narrowing part. The present invention relates to a commutator device for a small motor provided to narrow the lead portion of the armature winding by arranging the terminal portion in the narrow portion and to weld the lead wire and the terminal portion by resistance welding.
본출원인은 우선 소형 모터에 있어서의 전기자 권선과 정류자편을 접속함에 있어서 종래 행하여지고 있던 휴징방식이라고 불리우는 저항용접 방식을 채용할 경우의 결점을 해결하는 것을 제안했다. 그 제안은 단자부에서의 리드선을 압적하는 부분을 부분적으로 폭을 좁히거나 두께를 얇게하거나 하여 전기저항이 큰 부분을 마련하여 단자부의 꾸부러짐이 용이할뿐만 아니라 작은 전류치로도 바람직한 발열을 얻을 수 있고 또한 발열범위를 국부적으로억제할 수 있도록 하고 단자부와 리드선과의 도통 불량을 방지함과 동시에 열에 의한 절연원통의 변형도 방지하기에 가능한 소형모터의 정류자 장치를 제공하였다. 이하 상기 제안의 소형모터의 정류자장치에 대하여 설명한다.The present applicant first proposed to solve the drawback of adopting a resistance welding method called a fusing method, which has been conventionally performed in connecting an armature winding and a commutator piece in a small motor. The proposal is to provide a portion with a large electric resistance by partially narrowing the width of the lead wire in the terminal portion or to reduce the thickness thereof, thereby facilitating the packing of the terminal portion and obtaining desirable heat generation even with a small current value. In addition, the present invention provides a commutator device of a small motor that can locally suppress the heat generation range, prevent a poor conduction between the terminal portion and the lead wire, and prevent deformation of the insulating cylinder due to heat. Hereinafter, the commutator device of the small motor of the above proposal will be described.
제1도는 소형모터에 있어서의 정류자장치와 전기자의 관계를 도시하고 제2도는 상기 제안의 정류자 장치에 사용되는 정류자편의 한 실시예를 설명하기 위한 전개도, 제3도는 상기 제안의 정류자장치의 한 실시예 정면도 제4도는 상기 제안에 있어서의 리드선 접속상태(휴징 방식에 의한)의 한 실시예를 설명하기 위한 정류자장치의 측단면도를 도시하고 있다. 그리고 도면중의 부호(1)는 정류자장치, (2)는 정류자편(3)은 정류자부, (4)는 단자부, (5)는 전기자, (6)은 전기자권서, (7)은 리드선, (8)은 절연원통, (9)는 절연플랜지부 (10)은 절연왓샤, (11)응 협애부를 나타내고 있다.FIG. 1 shows a relationship between a commutator device and an armature in a small motor, and FIG. 2 is an exploded view for explaining an embodiment of a commutator piece used in the commutator device of the above proposal, and FIG. Example Front view FIG. 4 shows a side cross-sectional view of a commutator device for explaining an embodiment of the lead wire connection state (by a fusing method) in the above proposal. In the drawing, reference numeral 1 denotes a commutator device, 2 denotes a commutator element 3 denotes a commutator portion, 4 denotes a terminal portion, 5 denotes an armature, 6 denotes an armature certificate, 7 denotes a lead wire, Indicated by (8) is an insulating cylinder, (9) is an insulating flange portion (10) is an insulating washer, and (11) a narrowing part.
상기 제안의 정류자장치에 사용되는 정류자편(2)은 제2도에 그 한실시예의 전개도가 도시되어 없는 바와 같이 도시화살표 치수(a) 의 폭을 가지는 단자부(4)의 일부분에서 폭을 좁게한 협애부(11)가 형성되어 있다. 즉, 그 협애부(11)의 폭(b)은 단자부(4)의 기타폭(a)보다도 작게되어 있다. 그리고 도시생략하였으나 단자부(4)를 정류자부(3)에 대하여 직립하도록 도시점선부분에서 꾸부린다. 또 단자부(4)를 상기 협애부(11)에서 U자 형태로 꾸부린다. 이 경우 정류자부(3)를 절연원통(8)의 표면에 따르듯이 원호형태로 만곡시키고 있는 것은 말할 것도 없다. 그리고 정류자 장치(1)는 제3도 및 제4도에 도시되어 있는 바와같이 제2도에 도시되어 있는 정류자편(2)을 절연원통(8)상에 배치하고 절연왓샤(10)를 정류자부(3)에 감합시키므로서 고정 하도록 하여 구성되어 있다. 그리고 리드선(7)을 단자부(4)의 협애부(11)에서 협지하여 단자부(4)의 상방향에서 도시생략한 전극봉을 압압하고 당해 전극봉과 정류자부(3)상에 마련한 정극봉 사이에 전류를 흐르게 하므로서 상기 협애부(11)를 설치하지 않은 경우에 비하여 작은 전류를 흐르게 하는 것만으로 제4도 도시와같이 리드선(7)과 단자부(4)의 접속이 행하여 질수있도록 하였다.The commutator piece 2 used in the commutator device of the above proposal has a narrow width at a portion of the terminal portion 4 having the width of the arrow size a as shown in FIG. 2. The narrowing part 11 is formed. In other words, the width b of the narrow portion 11 is smaller than the other width a of the terminal portion 4. Although not shown in the drawing, the terminal part 4 is decorated at the dotted line portion so as to stand upright with respect to the commutator part 3. In addition, the terminal portion 4 is decorated in a U shape in the narrowing portion 11. In this case, it goes without saying that the commutator portion 3 is curved in the form of an arc as if it conforms to the surface of the insulating cylinder 8. The commutator device 1 arranges the commutator piece 2 shown in FIG. 2 on the insulated cylinder 8 and the insulated washers 10 are arranged in the commutator part as shown in FIGS. 3 and 4. It is configured to be fixed while fitting to (3). Then, the lead wire 7 is sandwiched between the narrow portions 11 of the terminal portions 4 to press the electrode rods not shown in the upward direction of the terminal portions 4, and a current is provided between the electrode rods and the positive electrode rods provided on the commutator portion 3. By passing through the current, the lead wire 7 and the terminal portion 4 can be connected as shown in FIG. 4 only by allowing a small current to flow as compared with the case where the narrow portion 11 is not provided.
그러나, 제2도 내지 제3도에 관련하여 설명한 정류자 장치의 구성만으로는 전기적 접촉불량을 일으켜 모터의 회전수가 변동하는 장해가 생겼다. 또 리드선을 협압하여 결합하는 결합력이 비교적 약하고 회전자의 조립, 운반, 취급, 모터의 조립등의 공정에서 예를들면 단자부가 벗겨지는 방향(여는 방향)에 외력을 받은 경우에 단자의 협압력이 한층 약해져서 전기적 접촉 불량을 일으키는 일이 있었다. 더우기 휴징에 의한 접속방식을 채용하는 정류자에는 일반적으로 열경화성 수지의 절연 원통이 사용되어 있으나 열경화성 수지는 코스트가 높고 대량생산성도 뒤떨어지므로 그리고 저렴하고 대량생산에 뛰어난 열가소성 수지의 절연원통을 사용하도록 하는 것이 요망된다.However, only the configuration of the commutator device described with reference to Figs. 2 to 3 has caused an electrical contact failure, resulting in a disturbance in which the rotation speed of the motor varies. In addition, when the external force is applied in the direction in which the terminal part is peeled off (opening direction) in the process of assembling, transporting, handling and assembling the motor, etc. It became weaker and might cause an electrical contact failure. Moreover, in general, the insulated cylinder of thermosetting resin is used for the commutator adopting the connection method by the fuse, but the thermosetting resin has high cost and inferior mass productivity. It is requested.
본 고안은 상기와 같은 휴징 방식을 채용할 경우에 있어서의 문제점을 해결하는 것을 목적으로 하고 있는 소형모터의 정류자장치를 제공하는 것이다. 그리고 그 제1의 목적은 단자부에 있어서의 리드선을 압접하는 부분에 부분적인 협애부(또는 육박부)를 마련함과 동시에 이 협애부에 리드선의 결합을 용이하게 하는 수단(리드선 결합용이화 수단)을 병용하여 상기 협애부에서 꾸부러져 상기 리드선을 협착하고 저항용접에 의하여 상기 단자부와 리드선이 저온도 또는 저압압력하에서도 바람직한 충분한 용접이 될 수 있도록 하고, 단자부와 리드선과의 도통불량을 방지함과 동시에 열에 의한 열가소성 수지의 절연원통이 변형하는 것을 방지하고 정류자와 리드선과의 결합강도를 증가시키는 것이다. 본 고안의 제2의 목적은 상기 리드선 결합용이화 수단으로서 단자부의 협애부에 마련한 선형 또는 점형을 한 다수의 요철부에 의하여 이 요철부의 파고들어감에 의해 정류자와 리드선과의 기계적인 결합강도를 증가시킨 구성을 채용하고 비교적 저온도 또한 저압압력하에서 휴징을 행할 수 있도록 하고 저렴한 열가소성 수지의 절연통을 사용가능하게 하는 것이다. 또한 본 고안의 제3의 목적은 상기 리드선결합 용이화수단으로서 단자부의 협애부에 저용융금속층을 피착시킨 구성을 채용하고 비교적 저온도 또한 저압압력하에서 휴징을 행할 수 있도록 하고 저렴한 열 가소성 수지의 절연 원통을 사용가능하게 하는 것이다.The present invention provides a commutator device for a small motor, which aims to solve the problem in the case of employing the above-mentioned fusing method. The first object is to provide a partial narrowing portion (or a thin portion) at a portion in which the lead wires are pressed in the terminal portion, and at the same time, a means (lead wire coupling means) for facilitating engagement of the lead wires in the narrowing portion. Used in combination with the narrowing part to squeeze the lead wire, and by resistance welding, the terminal part and the lead wire can be sufficiently welded even under low temperature or low pressure pressure, and at the same time to prevent poor conduction between the terminal part and the lead wire. It is to prevent deformation of the insulating cylinder of the thermoplastic resin by heat and increase the bonding strength between the commutator and the lead wire. The second object of the present invention is to increase the mechanical coupling strength between the commutator and the lead wire by digging into the uneven portion by a plurality of linear or pointed uneven portions provided in the narrow portion of the terminal as the lead wire coupling means. It is possible to fuse a relatively low temperature and low pressure pressure, and to use an insulated cylinder of an inexpensive thermoplastic resin. In addition, a third object of the present invention is to adopt a structure in which a low molten metal layer is deposited on the narrow portion of the terminal portion as the lead wire coupling means, to allow the fuse to be held at a relatively low temperature and low pressure, and to insulate the thermoplastic resin inexpensively. To make the cylinder available.

본 고안의 경우 제5도 내지 제11도에 도시하는 바와같이 소형모터의 정류자장치에 마련된 정류자편(2)의 단자부(4)에 협애부(11)를 마련함과 동시에 그 단자면에 리드선 결합용이화수단을 부가한 구성을 취하도록하고 있다. 그리고 제5도 내지 제7도에 도시하는 것은 리드선 결합용 이화수단으로서 단자면의 길이방향으로 직선형태의 철부 또는 요철부(12)를 나란히 한 구성을 가지는 것이며, 제8도에 도시하는 것은 리드선 결합용이화 수단으로서 단자면에 경사진 직선형태의요철부(13)를 형성한 구성을 가지는 것이고, 제9도에 도시하는 것은 리드선 결합용이화 수단으로서 단자면에 점형의 요철부(14)를 다수배치한 구성을 가지는 것이며, 제10도에 도시하는 것은 리드선 결합용이 화수단으로서 저용융 금속피착층(15)을 단자면에 구성한 구성을 가지는 것이고, 제11도에 도시하는 것은 리드선 결합용이화 수단으로서 상기 제7도 도시 요철부(12)와 제10도 도시 저용융 금속 피착층(15)을 단자면에 병설한 구성을 가지는 것이다. 또한 제11도 도시실시예에 있어서의 요철부(12) 대신에 상기 제8도 도시 요철부(13) 또는 제9도 도시 요철부(14)를 마련하도록 하여도 좋다.In the present invention, as shown in FIGS. 5 to 11, the narrowing portion 11 is provided at the terminal portion 4 of the commutator piece 2 provided in the commutator device of the small motor, and at the same time, the lead wire is easily connected to the terminal surface. It is trying to take the structure which added the fire means. 5 to 7 show a structure in which straight convex portions or concave-convex portions 12 are arranged side by side in the longitudinal direction of the terminal face as the means for coupling lead wires, and in FIG. It has a structure in which the straight concave-convex portion 13 inclined on the terminal surface is formed as the coupling sintering means, and shown in FIG. 9 is a point-shaped uneven portion 14 on the terminal surface as the lead wire coupling sintering means. The arrangement shown in Fig. 10 has a configuration in which the low-melting metal coating layer 15 is formed on the terminal surface as a lead wire joining means, and shown in Fig. 11 shows a lead wire joining ear. As a means, it has the structure which provided the said FIG. 7 uneven part 12 and the FIG. 10 low molten metal adhesion layer 15 in parallel with a terminal surface. In addition, instead of the uneven portion 12 in the FIG. 11 illustrated embodiment, the above-mentioned FIG. 8 illustrated uneven portion 13 or FIG. 9 illustrated uneven portion 14 may be provided.
상기 제7도, 제8도, 제9도, 제11드 도시의 각 실시예의 경우에는 제4도를 참조하여 설명한 바와같은 휴징을 행하였을 때에 상기의 요철부(12)나 (13) 또는 (14)가 리드선(7)에 파고들어가는 형태로 되어 보다 낮은 온도하에서도 리드선(7)과 단자부(4)와의 접속이 확실하게 된다. 더우기 제10도나 제11도 도시의 실시예의 경우를 고려하여 휴징에 있어서의 온도의 조건을 검토한다.In the embodiments of FIGS. 7, 8, 9, and 11th, the uneven portions 12, 13, or (or 14 becomes a form which penetrates into the lead wire 7, and the connection of the lead wire 7 and the terminal part 4 is ensured also at lower temperature. Furthermore, considering the case of the embodiment shown in FIG. 10 or FIG. 11, the conditions of the temperature at the fuse are examined.
동선을 휴징방식으로 용접할 경우 단자에 완전히 융착시키려면 동의 융점이1084℃인 것으로 보아 스폿트열은 최소한 1000℃ 이상이 아니면 안되는 것이었다.In the case of welding the copper wire by the fuse method, the melting point of the copper must be at least 1000 ° C because the melting point of copper is 1084 ° C in order to fully weld the terminal.
이에 대하여 본 고안의 경우 다음과 같은 온도로 족하다. 즉, 회전자의 권성에 통상사용되고 있는 리드선(7)의 피악인 수지의 피막파괴 온도는On the other hand, the present invention is sufficient as the following temperature. That is, the film breaking temperature of the resin which is the wicked of the lead wire 7 normally used for the winding of the rotor is
폴리우레탄 수지피막 120℃Polyurethane Resin Film 120 ℃
포리에스텔 수지피막 130℃Polyester resin film 130 degrees Celsius
이므로 150℃ 정도에서 전선피막은 완전히 파괴된다.Therefore, the wire coating is completely destroyed at about 150 ° C.
그리고 단자 피막의 전용융 금속의 융점은And the melting point of the exclusive molten metal of the terminal coating
주석 도금 232℃Tin plating 232 ℃
땜납 도금 180℃(최저온용융의 것)Solder plating 180 ° C (cold melting)
이므로 본 발명에 있어서의 단자면의 주석 도금피착층의 경우라면 250℃로 충분히 융착하고, 땜납도금 피착층의 경우라면 200℃의 열을 가한다면 충분히 융착된다. 따라서 본 발명의 경우는 휴징만의 경우보다도 낮은 온도로 처리되므로 열가소성 수지의 절연원통을 사용한 경우에 있어서도 휴징을 적용할 수가 있다.Therefore, in the case of the tin-plated layer on the terminal surface of the present invention, the film is sufficiently fused at 250 ° C, and in the case of the solder-plated layer, the film is sufficiently fused if heat is applied at 200 ° C. Therefore, in the case of the present invention, since the treatment is performed at a lower temperature than in the case of only the fusing, the fusing can be applied even when the insulating cylinder of the thermoplastic resin is used.
이상 상술한 바와같이 본 고안은 전자부에 협애부를 마련하는 것과 동시에 리드선 결합용이화 수단을 부가하였으므로 단자부가 꾸부리기 쉬울 뿐만아니라 정류자와 리드선의 결합강도는 단자부의 요철부가 리드선에 파고들어가 또 저용융금속으로 융착할 수가 있고 접속부분의 기계적으로 결합강도를 증가시킬 수가 있었다. 그 결과 회전자의 원심력에 의하여 전기적 접촉불량을 일으키는 일없이 모터에 회전 변동이 생기는 일이 없다.As described above, the present invention not only makes the terminal part easy to squeeze, but also makes the terminal part easy to bend as well as providing the narrowing part in the electronic part, and the coupling strength of the commutator and the lead wire is reduced by the uneven part of the terminal part. It could be fused with metal and increased the bonding strength mechanically. As a result, rotational variation does not occur in the motor without causing electrical contact failure due to the centrifugal force of the rotor.
또 결합이 강화되었으므로 회전자의 조립, 운반, 취급, 모터 조립등의 공정에 있어서 불의의 사고에 의하여 전기적 접촉 불량을 일으키는 일이 없다.In addition, since the coupling is strengthened, electrical contact failure is not caused by an accident during the assembly, transportation, handling, and motor assembly of the rotor.
더우기 저온도이며 또한 저압압력에 의한 휴징을 행하는 것이 가능하게 되었으므로 열경화성 수지보다도 저렴한 열가소성 수지의 절연 원통을 사용할 수가 있다.Moreover, since it is possible to fuse at a low temperature and at a low pressure, it is possible to use an insulating cylinder of a thermoplastic resin that is cheaper than a thermosetting resin.
